Python is a powerful programming language. It is very friendly and easy to learn. At writing time of this article Python 3.7.0 latest stable version is available to download and install. This tutorial will help you to install Python 3.7.0 on your CentOS, Red Hat & Fedora operating systems.
Step 1 – Requirements
This Python installation required GCC compiler on your system. Login to your server using ssh or shell access. Now, use the following command to install prerequisites for Python before installing it.
yum install gcc openssl-devel bzip2-devel
Step 2 – Download Python 3.7
Download Python using the following command from python official site. You can also download the latest version in place of specified below.
cd /usr/src wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
Now extract the downloaded package.
tar xzf Python-3.7.0.tgz
Step 3 – Install Python 3.7
Use below set of commands to compile Python source code on your system using altinstall.
cd Python-3.7.0 ./configure --enable-optimizations make altinstall
make altinstall is used to prevent replacing the default python binary file /usr/bin/python.
Now remove downloaded source archive file from your system
rm /usr/src/Python-3.7.0.tgz
Step 4 – Check Python Version
Check the latest version installed of python. Use command python3.7 instead of just python.
python3.7 -V Python 3.7.0
yum-builddep python36
Instalou sem erros, porem quando procuro na pasta bin junto com as outras versões não aparece.
E quando coloco python3.7 –version mostra como não instalado.
# python3.7 -V
bash: python3.7: not found
then
# whereis python
python: /usr/bin/python /usr/bin/python2.7 /usr/bin/python2.7-futurize /usr/bin/python2.7-pasteurize /usr/lib/python2.7 /usr/lib64/python2.7 /etc/python /usr/local/bin/python3.7m /usr/local/bin/python3.7 /usr/local/bin/python3.7m-config /usr/local/lib/python3.7 /usr/include/python2.7 /usr/share/man/man1/python.1.gz /usr/src/Python-3.7.0/python
and move label to directory which you need like it
cp /usr/src/Python-3.7.0/python /usr/bin/python3.7
try yum install libffi-devel if you have Python3: ImportError: No module named ‘_ctypes’ when using Value from module multiprocessing
You have to add following requirement too – yum install libffi-devel
